I know these are all arxiv.org so far, but if you want to include research papers beyond that plaform, can I encourage you to use DOIs for links? It'll make links persistent and easy to cross-reference with citations and other systems. I did a spot check of the 14 links you have so far all have DOIs. I'm happy to give advice!

I came here as well to recommend the DOI. So many nice things can be had by using this rather than your own IDs, it means that site now becomes a tool that composes with other tools.

I'm always interested in hearing about less-than-mainstream uses of DOIs.

The DOI is a natural foreign key, look at semantic scholar and the integrations that arxiv is doing in the bottom 1/3. You are generating your own IDs, so you won't compose with the rest of the ecosystem.

Your keys mean nothing and given a handle to a paper, they can't reference your site.

Hey @afandian, can I interview you about the tech stack you all used to build search at Crossref.org?

Always happy to share more details about how we build open scholarly infrastructure! Can do here, or reply with contact details.
